Yeah I'm a "me too" on the concern that the "back" button is too
hidden given it's frequent use. Perhaps we won't need "back" so
much in this new environment?
The System Settings design uses deep page stacks -- for example, five
levels deep when setting a background picture.

Discoverability of "Back" is my biggest concern with System Settings
right now. In a couple of cases I've specified that the toolbar should
be visible all the time: for example, the screen for choosing an area
of the background picture. But that's only because the toolbar
contains other buttons on those particular screens.
In any case, with gestures we need to be very mindful of how apps
are going to operate. We don't want to offer a gesture that might
look anything like something you might do in reasonable use of some
app that doesn't exist on this platform yet. Think about about
what you do on the screen when say, using a map, drawing a picture,
moving a piece in a game etc, etc. I think gestures coming in from
the edge are fairly safe, but the main screen area is for the
app...

A gesture might be more efficient than revealing the toolbar then
tapping Back. But I doubt it would be more discoverable.
